LAND AND FRESHWATER 



which species, together with a yet unpublished form found by 

 Major Godwin-Austen in the Khasi Hills, are its nearest allies. 

 In some specimens, taken alive, the costulation has disappeared 

 from the greater portion of the upper whorls, and remains only in 

 l)atches ; so that on a cursory inspection, the whorls appear to be 

 smooth and striate ; it is most distinct on the inflated portion of 

 the shell. 



" I found a single specimen of this shell in 1856, in the Kungno 

 Valley. Some years afterwards I received several specimens from 

 Mr. W, S. Atkinson, which were taken, I believe, near the station 

 of Darjeeling." 



In W. T. Blanford's collection there are two specimens 

 (No. 48.0(3.4.4) named A. Jimbriatus, a M8. name, for I have 

 failed to find it alluded to in any paper by Elanford. The specimens 

 are bleached and poor and represent a dwarf variety of A. digitatns, 

 H. Elf., found in a neighbouring valley to Darjiling, the llungun.

" 6, Eungun Valley, Darjiling, ex coll. Dr. F. Stoliczka & Col.

 compared with the type in Mr. W. T. Elanford's collection 

 (No. 55.06.4.4 E.M. Coll.).

Only a single specimen is in the Indian Museum, Calcutta ; it is 

 allied to A. lenticulus, but has distinctive characters.
